2)Remove all partitions of SD card and format it with FAT32 etc. (I used Windows Disk Management)
3)Download win32diskimager and install it. https://sourceforge.net/projects/win32diskimager/<>
4)Execute win32diskimager, select SD driver, load the .IMG file and press "Write" button to proceed.
5)Once the image is burned, insert the SD into New Bittboy and turn it on. If it boots it is a success.
6)You can expand you main drive to reclaim the full space use partition magic or similar app.

How to tell between V1 & V2 Bittboy?

Well you will probably know by now there are 2 revisions of the bittboy V1 & V2 the only difference being is V2 is more user friendly installing the CFW. The way to tell externally is if you press the start & select buttons if they are soft its V1 if they have a clicky feel to them then its V2. If you want to dig a little deeper and make sure remove the 6 screws and on the top right where the sd card is situated you will see the words V2.0 or on v1.0 there is no marking on the board.

Some of the emulators need the ability to remap buttons, I.E. Gpsp is missing this functionality. So for example when you're playing Super Mario World GBA and you hold down B and then press A to jump, while holding right, it drops down your extra item that you're holding in the box at the top, acting as if you're pressing select. Being able to remap these buttons might fix this issue.
